IMPROVEMENT IN CAR-SEAT ARMS.

Specification forming part of Letters Patent No. 151,470, dated June 2,1874; application led September 5, 1873.

To all 'whom it may concern:

Be it known that I, W. J. CALAIS, of the eity'of Wilmington, State ofNorth Carolina, have invented an Adjustable Car-Seat Arm, of which thefollowing is a specification:

The object of my invention is to connect or disconnect the car-seat armA (refereneebeing had to the accompanying drawing) with back T andarm-rest V easily and rapidly, without the removal and replacement ofscrews, and consequent scratching and defacing of parts and loss oftime.

Figure l shows a broken plan of adjustable arm A; Fig. 2, a longitudinalsection of arm A, connected with back T by spring-bolt B, and with anarm-rest, V, by spring-bolt O. Fig. 3 shows an outside View of arm A inplace in socket-plate m, by which it is connected with back T; also, aninside view of arm A, connected with plate n, by which it is attached toarm-rest V.

g represents the spring of bolt B. f represents the spring of bolt C.

To disconnect arm Afrom back T, draw out spring-bolt B by its head, sothat its smaller diameter L can pass out through slot w.

To disconnect arm A from arm-rest V, draw out spring-bolt C by its head,so that its smaller diameter av can pass through slot finto larger holec, through which the head of bolt C can pass.

When arm A is connected with arm-rest V, by giving bolt C a half-turn.pins is turned away from slot o, by which means bolt C is held irmly inplace, and cannot be Withdrawn. A half-turn of Vbolt B removes pin pfrom slot 1', for a similar purpose.

I claim as my invention- In combination with the adjustable arm A,having slots w and e, the 'movable bolts B and C, substantially as andfor the purposes set forth.

W. J. CALAIS.
